RCG Racing Tracer / MT-One プラスチックピボットボール コンプリート

The pivot balls fit perfectly into the MT-One arms with zero slop, which is exactly what I needed after stripping my old ones. Also nice that they double up for the FTX Tracer, so I've got spares for two cars now.

Cheaper than buying the same part elsewhere and the fit on the suspension arms is spot-on, no filing needed. Plastic feels a bit stiff but that’s fine for a spare that sees regular dirt and jumps.
